Thank you, Richard! The biggest effort is to create all of the symbols which don’t exist in much of the newer circuit software. It was a labor of love, but I’m happy to share what I find. I plan to get this schematic updated with all of my findings after going through the chassis. I’m always afraid to start disassembly until I am absolutely confident that I have the documentation to put it back together correctly.

Is there a reference somewhere where you can punch in Philco part numbers and see what models those parts were used in?Jim Dutridge — 10:17 AM |

Hi OSanders,
Look carefully at the band switch. Turn it slowly and "wiggle" it around the desired band. ...MrFixr55 — 12:33 AM |
